Tuya Smart BLE Module

1. Product Overview

TYBT5 is a Bluetooth (BLE) module designed by Hangzhou Tuya Information Technology

Co., Ltd. The BLE Module consists of a highly integrated wireless Bluetooth chipTLSR8267 and

some extra electric circuits that have been programed with Bluetooth network protocol and plenty

of software examples. TYBT5 include a 32-bit MCU, BLE，512K byte flash，16K byte SRAM

and 9 multiplex IO pins. Users can customize their LED products by using these PWM signals.

TYBT5 user manual 5. Antenna Information 5.1 Antenna Type Antenna can be connected using On-board PCB antenna only. 5.2 Reduce Antenna Interference In order to have the best RF performance, It’s recommended to keep a minimum 15mm distance between the antenna part and the other metal pieces. Since PCBA manufacture use SMT process to weld TYBT5 module and other electrical components onto the PCB board, RF performance will depend on the layout location and pattern of the On-board PCB antenna.
